Troubleshooting
WARNING:
To avoid injury or loss of life, pay attention to any hazardous voltage
(For example, 120 Vac) when performing checks.
• Check that the wires are connected correctly.
• Check that span/offset (start point) and Dip switches are set correctly, if used.
• Use a Digital Multimeter (DMM) to verify that the operating voltage is within range.
• If the actuator is not working, check the damper for blockage. If blocked, remove
the obstacle and cycle the actuator power off and on. The actuator should resume
normal operating mode.
